Abstract
[Objective] The chemical components and its relationship with appearance quality and the smoking quality were discussed.[Method] The chemical components,smoking quality and appearance quality in tobacco leaf samples of 4 counties in Yibin City were measured and discussed with correlation analysis and multiple comparison.[Result] The results showed that Yibin tobacco leaf total nitrogen,nicotine and potassium contents were appropriate; Total sugar and reducing sugar content were slightly high,chlorine was slightly low; In Xinwen County,the tobacco appearance quality was better in Baiaolin Village,smoking quality was better in Xiaozhai Village; Total sugar content had significant positive correlation with color and oil content,and extremely significant positive correlation with identity; Potassium had significant negative correlation with oil,chroma,aroma quantity and finish,extremely significant negative correlation with maturity; Total nitrogen content had significant positive correlation with physiological strength and smoke concentration,and extremely significant negative correlation,and aroma quality and offensive odor.[Conclusion] Appropriate cultivation and management measures should be taken in production to decrease the nicotine and total nitrogen content,and increase the total sugar and reducing sugar content in tobacco leaves.关键词
